Application filed March 10, 1926. Serial No. 98,638.

My invention relates to railway car axles and has for its principal object a' construction which is simple and economical to manufacture, to assemble and dismount and to repair. The invention consists principally in a railway car axle construction Acomprising an; axle housig and a two part axle "therein, the inner ends of sald axle sections being spaced apart and supported by conical roller bearings, the two roller bearings having a common cup or outer bearing-member thatis loosely disposed in the axle houslng, so as -to be capable of movement therein.

The accompanying drawing is a sectional View of a railway car axle construction em. hodyingmy invention. 4

Axle .sections 1 having wheels 2 on their outer ends are disposed in an axle housing 3. The inner ends 4 of'said axle sections l are spaced apart. Mounted'on the inner end 4 of each'axle section is the cone-5 or inner bearing member of a conical roller bearin In the drawing the end portions 4 of t e axle sections 1. are illustrated as beingreduced in diameter, so that each cone 5 abuts a ainst a shoulder (j on its-axle section. A oubly coned cup 7 or outer bearing member is loosely disposed in the' axle housing 3. Preferably the portion oi the 4axle housing 3 in which said cup is mount-V ed comprises van inner peripheral band 8' that is machined or otherwise smoothly iinished, vand the outer surface 9 of the cup 85 7 is likewise smoothly finished, so that the cup 9 is free to slide in its mounting. Conical rollers 10 are interposed between the conical raceways of the cup 7 and the respective cones..

The outer end 4 of each axle section is preferably provided with a shoulder 11 disposed inside of the housing 3,'against which shoulder abuts the cone 12 or' inner bearing member of a conical roller bearing. The

l 4o Cup 13 or outer bearing member therefor is mounted in the end of the axle housing 3 and conical rollers 14 are inter osed between the cup 13 and cone 12. ach end of the axle housing is Erovided with an end closure ring 15 that as an inwardl extending'annular rib 16 that abuts a ainst a cup 13. Shims 17 are interposed etween each ring 15 and the -end of the housing so as to permit ad'ustment of` the bearings.

Il The truck side rames 18 rest on the end of the axle housing abovethe louter conical roller bearings.

The 'floating t of the double cup of the p inner sets of roller bearings permits thrusts c to be transmitted from one end of the axle 6o to the-other. `It likewise permitseasier adjustment of all'of the bearings. The axle housing is -simple toeconstruct and requires a minimum amount ofexpensive machining work. Either yaxle section may 'easily bel e5 removed for repair or replacement.

What I claim is:

-1. A railwa car axle construction comprising an ax e housing and axle sections therein, and a sup ort in said housing for 4 the inner ends'of sa1d axle sections, said supportbeing slidable in said housing.

2. A railwavk car axle construction comprising an'ax e housing, axle sections disposed in said housing, and conical roller bearinos interposed between the inner ends of said axle sections and said axle housing, said. conical roller bearings'having a common outer bearing member, saidouter bearin member being loosely mounted in said s ax e housing. f

3. A, railwa car axle. construction comprisingan ax e housing, axle sections dise posed in said housing, conical roller bearings interposed between the outer ends of the axle sections and the outer ends of said housing, conical roller bearings interposed between the inner ends of said axle sections and said axle housing,.said last mentioned conical roller bearings having a common ou outer bearing member said outer bearing Y memberbeing loosel mounted in said axle housing, and means or adjusting said bearings.

-4. A railway car axle construction comprising an axle housing, axle section disosed in saidhousing, conical roller bearings interposed between the outer ends of the axle section and the outer ends of said housing the rollers of said bearings being dis osed with their smaller ends outermost :an the cones thereof abutting against shoulders provided therefor on said axle sections, conical roller` bearings interposed between the .inner ends of saidpaxle sections and said axle housing', said'last mentioned conical roller bearings having a common outer bearing member said outer bearing member being loosely mounted in said axle housing, and closure members in the ends of said llo Amnesia; COPY housing said closure members having portions abutting against said cups of said outer bearings.

5. A railway ycar axle constructlon 'com- 5 prising an axle housing, axle sections there- 1n, a supportin said housing for the inner ends of said axle sections, said support being slidable in said housing, and .antifriction rollers interposed between the inner ends of said aXle sections and said support 10 therefor.
